docker-compose部署kafka集群遇到jvm out of memery问题

利用docker-compose部署kafka集群遇到内存不足问题，报错信息中有如下信息：

kafka_1_a6f53db08f56 | # Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
kafka_1_a6f53db08f56 | # Can not save log file, dump to screen..

kafka_1_a6f53db08f56 | # Possible solutions:

可以看出默认的堆大小为1G，所以在机器配置较低时内存会不足。

在docker-compose.yml  wurstmeister/kafka默认没有配置jvm参数 可以使用 KAFKA_JVM_PERFORMANCE_OPTS 指定jvm参数调整堆栈大小
